You can't open Mariachi '10 shop because it's a seasonal rare, you cannot open seasonal rare shops if they're not in season (i.e. you can't open Mogloween shops if it's not Mogloween, you can't open Frostval shops if it's not Frostval, etc)

Don't know ID of Chronomancer shop, I'll check later. If you buy Chronomancer, you'll get banned because AE has caught on to hackers of Chronomancer.

Used to be that there were a lot of hacks you could use, but AE (Artix Entertainment) patched them. Really, the only things that are safe for you to use are the quest and shop loaders, and even then there are a few quests or shops that can ban you if you turn them in or purchase certain items. What I'm trying to say is that there USED to be a gold hack that worked, but AE patched it, so to sum it up....
